Moisture meter Humidity Meter PH meter light meter moist light PH 3in1 soil PH meter for Garden Plant Flower

Scientific farming methods, is that we keep a good basis for flowers. After reading some friends after gardening Cheats, unfortunately, shaking his head, how do I know the soil pH ah; I could not estimate soil moisture; in the end how much light is appropriate. Now with three soil tester pointed out the direction for you, so you love to spend their own living environment have a basic understanding. Keep a good flower, but it is crucial oh

Triple measure soil moisture tester / PH / illumination
Size: 290 * 50 * 38MM
Probe Length: 200mm
Weight: 90g
This paragraph instrument is a good helper for gardening, you can test the soil PH value (pH), soil moisture and light intensity. Need batteries.

Product Features
Low price, high quality, used for soil moisture, pH and light intensity measurements, gardening is a good helper; no batteries, we use the convenient

Precautions
1 Note that when using plug electrode must not touch the stone, do not use too much force, otherwise easily damage the electrode.
Promptly after use to clean the electrodes. (Non-directly into the water measurement).
2 can not be inserted in the soil long-term use! To avoid damage.

How to use:
PH value of the soil and humidity measurements, the first probe as deeply into the earth, leaving the upper part of the probe about 1 cm.

Toggle button on the pen to MOIST, MOIST is water key, the corresponding table is MOIST, DRY dry, WET wet, numeric 1-3 (the red part) the need watering, 4-7 (green part) is appropriate, depending on the plant species to adjust watering time, 8-10 (blue section) description is too wet.

Toggle button on the pen to the PH, PH is pH keys on the table is 8-3.5 corresponding values, ALKALINE is an alkali, ACDIC is sour, the value 7 is basically neutral, the smaller the number the greater the acidity, according to the plant species adjust soil pH.

LIGHT button is the light intensity, range 0-2000 lumens, the greater the value, indicating that the light is stronger, according to the plant species to determine the need for shade.

Soil pH
Soil pH, also known as "soil reaction." It is the soil solution of the acid-base reaction. Mainly depends on the concentration of hydrogen ions in the soil solution at pH values. pH of the solution is equal to 7 neutral solution; pH of less than 7, the acid reaction; pH value greater than 7 is alkaline reaction. Soil pH can generally be divided into the following levels:

pH of soil pH
<4.5 strong acidic
4.5-5.5 strongly acidic
5.5-6.5 Acid
6.5-7.5 neutral
7.5-8.5 Alkaline
8.5-9.5 strongly alkaline
> 9.5 strong alkaline

Soil pH on soil fertility and a great influence on plant growth, China\\\'s northwest, north many soil pH value, pH value of small red soil. Therefore can be grown and adapted to soil pH and plant crops. Such as acid red soil area planted hi tea, and strong alkali such as alfalfa. Soil pH effects on nutrient availability is also great, such as neutral soil phosphorus availability large; alkaline soil trace elements (manganese, copper, zinc, etc.) effectiveness is poor. In agricultural production should be noted that the pH of the soil, and actively take measures to adjust.
